Qual das seguintes extensões das Leis
de Mendel descreve um padrão de
herança em que nenhum alelo é
completamente dominante sobre o
outro?
Alelos Múltiplos
Dominância Incompleta e
Codominância
○ Herança Ligada ao Sexo
Interações Gênicas



Answer :

Final answer:

Incomplete Dominance and Codominance explain patterns of inheritance where no allele is completely dominant over the other.


Explanation:

Incomplete Dominance and Codominance describe patterns of inheritance where no allele is completely dominant over the other. In these cases, the alleles interact to produce a phenotype that is a blend of the two.

Examples: In incomplete dominance, a cross between a red rose (RR) and a white rose (WW) results in pink roses (RW). In codominance, a cross between a black chicken (BB) and a white chicken (WW) results in offspring with both black and white feathers (BW).

These patterns of inheritance show the complexity beyond Mendel's simple dominant and recessive traits.
